We describe a case of neuroblastoma presenting as a paratesticular mass in infancy. To our knowledge this is the first case of a paratesticular neuroblastoma reported in the literature. An operation combined with radiotherapy and chemotherapy has achieved long-term survival despite obvious multifocal disease. Seven years after treatment of the inital tumor the patient presented with a subependymal giant cell astrocytoma, an extremely rare neuroectodermal tumor. Discussion is directed to possible explanations for this unusual case of multifocal, metachronous neuroectodermal neoplasms.

Background: Retroperitoneoscopic surgery (RS) is increasingly used for the diagnosis, staging, and treatment of solid tumors, but rarely in pediatric surgical oncology for retroperitoneal lymph node dissection (RPLND). Herein, we use single-site RS for RPLND in children and compare the perioperative outcomes with those for the transperitoneal laparoscopic approach (TPLA).
Methods: A single institution retrospective chart review was performed for patients undergoing single-site RS and TPLA (January 2018 till June 2019).

Background: Neuroblastoma (NB) is the most common extracranial solid tumor of childhood. Primary and secondary testicular involvement is extremely uncommon in neuroblastoma.
Procedure: All children with neuroblastoma treated with the Turkish Pediatric Oncology Group (TPOG)-Neuroblastoma (NB) Study and who had testis involvement either at diagnosis or at relapse were retrospectively evaluated.

The spectrum of testicular tumors and tumor-like lesions that affect young patients (defined for purposes of this article as less than 20 years old) differs significantly from that in an older age group. Although germ cell tumors remain the single largest category, they are a smaller proportion than in adults. Furthermore the pathogenesis and behavior of comparably named germ cell tumors differ depending on whether or not they have developed in prepubertal or postpubertal patients.

Primary neuroblastoma as a paratesticular tumor is extremely rare with only 8 described cases worldwide. In this article, we present the case of a 5-month-old boy with this rare tumor location and give an update on the current literature. As in our case, typically these tumors present as Stage 1 disease and simple tumorectomy alone leads to excellent outcome and long-term survival.
